Gang Saw Blocks
An improved vertical gang saw is provided for sawing blocks of stone or the like. By this new design, the vertical saw frame is slued or swung about the center of the blades during each reciprocating movement. This design combines the following features: the vertical frame being supported at the center; straight line guides connected to said frame and positioned respectively at one end and in the center of the saw frame; and the pivotal point of the straight line guide being moveable perpendicular to the stroke of the frame and dependent thereupon.

The perpendicular movement of the straight line guides can be accomplished by connecting them with a cam which is driven off of the flywheel . Through this combination, all of the saw blades cut the stone block workpiece in both the up and down directions. .
